qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

[IanH222]

It's loaded as part of a python script, and the problem is in matplotlib code.

It looks like it's potentially a problem with PyTorch's DataLoader using threads, and then me asking matplotlib to imshow some data that was originally loaded on a different thread. But I can't go much deeper than that because the rest is all in libraries.

@IanH222
I know that you must not try to do any Qt UI stuff in anything but the main thread, but I don't know how that relates to whatever you are doing in matplotlib.

Thanks, appreciate the help. I'll ask in the forum for this code snippet.
